I just finished reading the third book of the Percy Jackson and the Olympians series by Rick Riordan.
So far I have really liked the books. I find them funny, well-written, fast-paced and imaginative. Riordan writes with grace and ease, yet I felt that there was some topics he avoided, as if he didn't know how to handle them (such as a distinct lack of emotion, and how the whole prophecy-thingy easily gives away more information than Riordan really was ready to spoil), leaving some awkward bits here and there.
This is why the first two books only got four stars from me.
The third book, however, was better. The story gets a little darker, and Riordan seem to face some of the problems more seriously. This resulted in me getting less annoyed and focusing more one the story plot, giving me the chance to feel the thrill and the ride of the story.
This series is picking up its pace, and I am eager to read the rest to se how it ends!
